摘      要：Isothermal thermogravimetric analysis was used to study the reduction process of solid/liquid wustite by *** show that wustite in both states can be reduced entirely at all *** thermal and kinetic conditions for the hydrogen reduction of molten phases are better than those when the reactants and products are in the solid state,with a higher reaction *** hydrogen reduction of different wustite phases fits the Mampel Power model(power exponent n=1/2)well,and this model is independent of the phase *** average apparent activation energies of the reduction process calculated by the iso-conversional method are 5.85 kJ·mol^(−1) and 104.74 kJ·mol^(−1),when both reactants and products are in the solid state and the molten state,*** values generally agree with those calculated by the model fitting method.
